Lilac

Lila or Lilac is one of Tsubaki's subclasses.

Ambush at Licht's Concert
One of the weaker subclass, Lila and his friends, Kaede and Kashi, were tasked with filling the entire concert hall while the other subclasses killed the Greed pair during Licht's concert. Lila was actually reluctant to join and even contemplated not to after Tsubaki told him there's no need for him to join if he doesn't want to, but relented because his friends persuaded him. But Lawless proved to be too powerful for them, leading the Servamp to annihilated most of the subclasses inside the concert hall. Lila was the only subclass who was tasked inside the concert hall to survive the massacre, hiding under a seat while Lawless is fighting against Kuro. After the fight, Lila tries to escape, but accidentally makes a sound and gets found out. Lawless attempts to kill him, but was stopped by Mahiru. Still in shock, Lila apologises and begs Mahiru not to kill him. Mahiru assures him that he won't and offers his hand so he can stand, earning Lila's trust and the subclass thanks him for saving him from Lawless.
